Plankton from Green Lochan, Aviemore. August, 2000.


Green Lochan is in the Scots pine (Pinus sylvestris) forest on the edge of the Cairngorms. The soils are shallow and gravelly, and the lochan appears to be nutrient-poor (no assays have been done), its chemistry probably dominated by the geology. The waters are very clear, the bottom covered with stones and fallen logs. There are few macrophytes present.
